Lake Somal is the largest lake in the Westlands. It lies between Paerish Swar and the Mountains of Mist, southeast of Arad Doman and east of Almoth Plain. Despite its size it is somewhat remote and relatively unknown, although a trading road links it to the city of Katar a hundred miles or so to the northwest. Some maps show the lake as being the source of one of the many tributaries of the River Andahar.
The Dragonsworn used the area as a base of operations during their war against Arad Doman. They were defeated in a battle on the lakeshore by General Rodel Ituralde, but orders from King Alsalam Saeed Almadar meant that the victory could not be completed.
